EDWARD M. DEEMS, OF FOREST HILLS, NEW YORK.

To all whom t may concern:

Be it known that I, EDWARD M. DEEMs, a citizen of the United States, and resident of VForest Hills, in the county of Queens and State of New York, have invented Vcertain new and useful Improvements in Rail- Bonds, of which the following is a specification.

This invention relates toimprovements in electric bonds for railway rails, and it has for its principal object the provision of a bonding wire bent to standard form and size, and provided with means for holding it in proper shape and sustaining it in the desired position when applied to the rails. Y Another object of the invention is to provide a bonding Wire of standard form and size, with flexible reinforcing means adapted to bridge the joint between the bonding wire and the bonding pins by means of which the wire is secured to the rails, said flexible means being rigidly connected to the bonding wire.

Another object of the invention is to provide a bonding wire of standard form and size, with a reinforcing means of wire coiled about the horizontal members of the bonding wire in such position as to bridge the joint between the wire and the bondingpins, said coiled wire reinforcing means being extended upwardly and having one end coiled about the main longitudinal strands of the bonding wire,V so that said strands will be sustained in an elevated position.

A further object of the invention is to provide a bonding wire with means connected to the entering and supporting ends of the wire and to the main body portion of the wire to sustain the said body portion and maintain it in proper form and prevent it being damaged and broken.

Another object of the invention is to provide a bonding wire of standard form and size and to connect the entering ends of the bonding wire with the body part thereof by a reinforcing and sustaining element, the said reinforcing element forming a permanent part of the bonding element. A

There are other important objects and advantages of the invention which will appear hereinafter. l

The rail ends are apertured atpoints beyond the splice bars for the reception of the ends of the bonding wires, and the bonding pins which secure the bonding wires to the rails.v

The bonding element is formed of two strands of wire bent to form the main upper horizontal portion 4:,Which, atl its ends, is

bent Vdownwardly and then carried inwardly to form the inwardly.extendinglower horizontal portions 45, said inwardly-bent portions forming-,the loops 6; yAt ythe inner ends of the horizontal portions 5 the Wires are bent at right angles to the vertical plane of the body portion 4 of the bonding element to provide theconnecting members 7 which are adapted to be extended through the ap-4 ertures in the rails. Coiled about the connecting members 7 are the reinforcing elements 8. These elements are formedof a wire coil, and are of suilicient length to cover a substantial portion of the connecting members. One end of the wire forming the reinforcing element 8, preferably that end which is close to the rail web when the device is in position, is extended upwardly and coiled about the main body 4 of the bonding clement, as at 9. The coiled reinforcing element S is rigidly secured to the connecting members 7 by solder 1,0, or any other suitable means, said connection being made at a point near the outer ends of the connecting element, as shown clearly at the left-hand end of Fig. 2. 'Y

The coils 9 are preferably located on the body, portion 1l of the bonding element, at points inward of the ends of the loop 6, that is to say at points inward'beyond the sustaining members 7. The saidy reinforcing and sustaining elements comprising coils 8 Vand 9. and the connecting, portionform a bridge between the entering -ends and the main body portion, and form a permanent part of the bonding element.

vthe railway ties The ends of the connecting elements 7 are first passed through the apertures in the rail ends and are bent over in opposite directions and broughtto bear against Vthe sur-face of the rail web. The bonding pin 11 is then driven into position, the end of said bonding pin entering the reinforcing element 8 thereby expanding the reinforcing element and causing said element and the bonding wires and the bonding pin to be intiinateiy connected.' rlhe reinforcing element bridges the joint between the end'oi the bonding pin and the bonding Wires, and forms a resilient reintorcing ineans at'that point. By rigidly and permanently connecting the reinforcing element to the'V entering members of the bonding wire, the said coiled element will maintain its position on the bonding wire so that the end of the'v bonding pin may be driven into it. The body part 'of the bonding wires will be sustained inl lan elevated position above the nuts 3 and close to the face of the splice-bar, so that the nuts may be manipulated in the usual way without damage to the bondingVV wires. The coil 9 V'toiins a resilient support for the main body part of the bonding element and sustains it out of contact with the ground and above on which the tracks are supported.

Y'-(loiled', flexible reinforcements S talreup the vibrations ni the ybonding wires and prevent thebreaking of the bonding wires at points adjacent the ends or the bonding pins, and at the saine time securely 4hold the bonding wires 4in close engagement with the bonding pins. lThese reinforcing elements also'ser've as a' means for increasing the electrical contact between the bonding wiresand the bondingpin. The reinforcing supporting coils 9 hold the main portions oit' the bonding clement in intimate contact witheach-.otheigwhile at the saine time permitting the wires to respond to the vertical vi-4 brations therails.
